Deformability and settlement reduction characteristics of strip foundation composed by the layers of geo-textiles on the urethane ground model

Abstract

The experiment al study was carried out for the purpose of investigating the structure of geo-cell using the urethane ground model and various kinds of geo-textile models. Improvement of soft ground and reduction of settlement of strip foundation by the geo-cell is targeted to study. Especially extensional rigidity and combination of geo-cell and geo-textile is focused on. The experimental behavior by the urethane ground model test s is analyzed as the fundamental references. The model test gave the ordinary results that the higher the rigidity of geo-textile is, the larger the reduction of settlement level is. This improvement effect show efficiently when geo-textile is installed in the tension zone of strip foundation. It is necessary to extend the result to develop the geo-cell structure as the stripe foundation. Hence the test result s is tried to interpret roughly by the elastic theory applied for the stripe foundation. It is expected to the prototype scale, actual materials, combination and piling through the elasticity.
